Manitoba Naturalization and Citizenship
Until 1947, British immigrants from England, Scotland, Wales, and Ireland automatically became citizens of Canada. They did not need naturalization. Non-British immigrants, however, were required to make oaths of allegiance before receiving land grants. Files containing these oaths and petitions for citizenship covering the years 1817 to 1846 in Manitoba are found at the Provincial Archives.
Records created after 1917 are more detailed than earlier records and are found at:
